SAN ANTONIO — There’s a major Batman storm brewing at comic shops this Thanksgiving holiday. “The Dark Knight III: The Master Race” debuts Wednesday with a Batcaveful of variant comic covers — two of which you can only buy from San Antonio stores. And here’s your chance to see those exclusive covers, along with preview pages from the upcoming comic.

A special “Dark Knight III” cover by legendary comic artist Tim Sale is available exclusively at Heroes & Fantasies. The other S.A. variant features art by sci-fi/fantasy artist Dave Dorman and is exclusive to the online-only shop, M&M Comic Service. H&F will also offer a Dave Johnson variant, though this one sells at other comic stores as well.

“Dark Knight III” marks the return of Frank Miller to his mad, mad, mad, mad world of the Caped Crusader, which he launched to critical acclaim with his seminal 1986 miniseries, “The Dark Knight Returns,” only to later run into the ground with his blaring 2001-2002 sequel, “The Dark Knight Strikes Again.” Seriously, you won’t find a more glaring drop-off in quality than maybe hopping from “The Matrix” to “The Matrix Reloaded.”

At least with “Dark Knight III” there are some quality names onboard to help save Miller from himself. “The Master Race” is co-written by “100 Bullets” mastermind Brian Azzarello, with art by the talented Andy Kubert and Klaus Janson. “Dark Knight III” will run eight issues, each with a 16-page mini-comic featuring a rotating roster of guest artists.

Variant covers come in limited quantities, so expect to pay more for these editions than the standard $5.99 cover price for the comic. H&F’s Sale cover goes for $19.99, while the Johnson cover runs $9.99. M&M has the Dorman cover in color for $11.25 (limited to 3,000 copies), or you can get that along with a rarer black and white version (only 1,500 copies) both for $30. All the comics should have the same pages inside.

For more H&F fun, the comic chain’s Loop 410 location will ring in Black Friday with Santa Claus and other superheroes dressed in their holiday finest for Christmas photos. Then Saturday belongs to the Dark Knight with Batman and Superman cosplayers striking poses from the duo’s more memorable clashes, along with various Batman movies playing in the store.
